Create New Bun Package Repo

Create New Bun Package Repository

Expert guide for creating new Bun packages from the zenobi-us/bun-module template repository. Automates repository creation, cloning, and setup using GitHub CLI. Important: Setup runs with defaults (not interactive prompts).

Overview

This skill provides a complete workflow for bootstrapping new Bun packages using the bun-module template. The template includes TypeScript configuration, testing setup, and standardized module structure. The workflow handles repository creation via GitHub CLI, cloning, and running the setup script which applies defaults automatically.

When to Use

Use when:

• Creating a new Bun TypeScript package or library
• Starting a new Bun module project
• Need consistent package structure across projects
• Want automated GitHub repo setup with Bun template

Don't use for:

• Non-Bun projects (use appropriate template)
• Existing repositories (template is for new projects)
• Projects not requiring TypeScript or testing infrastructure

Important Limitation: Setup script runs non-interactively - you must manually edit package.json after creation to set correct name, description, and author details.

Quick Reference

Complete Workflow

Prerequisites Check

Before starting, verify:

# GitHub CLI installed and authenticated
gh auth status

# Bun installed (required for setup.sh)
bun --version

Step-by-Step Process

1. Gather Information

Ask the user for:

• Owner: GitHub username or organization (e.g., zenobi-us)
• Repo name: New repository name (e.g., my-awesome-module)
• Visibility: Public or private (default: public)

2. Create Repository from Template

# Public repository (recommended for open source)
gh repo create OWNER/REPO-NAME \
  --template zenobi-us/bun-module \
  --public \
  --clone

# Private repository (if needed)
gh repo create OWNER/REPO-NAME \
  --template zenobi-us/bun-module \
  --private \
  --clone

The --clone flag automatically clones after creation.

3. Navigate to Repository

cd REPO-NAME

4. Run Setup Script

bash setup.sh

The setup script will:

• Apply template files to current directory
• Replace template variables with defaults
• Remove old git history and template files
• Initialize fresh git repository
• Create initial commit
• Attempt to push to remote (may fail if repo just created)

Note: The script runs non-interactively and uses these defaults:

• Package name: my-bun-package
• Description: A Bun package
• Author: Your Name <you@example.com>
• Repository URL: Detected from git remote (usually correct)

You must manually edit package.json after setup to correct these values.

5. Update package.json Manually

The setup script uses defaults, so you must edit package.json:

# Edit package.json - update these fields:
# - name: Change from "my-bun-package" to your actual name
# - description: Update to your package's description
# - author.name: Your actual name
# - author.email: Your actual email

6. Trust mise Configuration

# Required before running mise tasks
mise trust

7. Install Dependencies and Build

# Install dependencies
bun install

# Build the package
mise run build

# Verify build succeeded
ls -la dist/

8. Commit Updates

# Stage package.json changes
git add package.json

# Commit your customizations
git commit -m "chore: update package metadata"

# Push to remote
git push -u origin main

Command Options

GitHub CLI Repository Creation

gh repo create [<owner>/]<name> [flags]

Key flags:

• --template OWNER/REPO: Use repository as template
• --public: Create public repository (default if using template)
• --private: Create private repository
• --clone: Clone repository after creation
• --description DESC: Repository description
• --homepage URL: Repository homepage URL

Examples:

# Minimal - public, auto-clone
gh repo create zenobi-us/new-module \
  --template zenobi-us/bun-module \
  --public \
  --clone

# With metadata
gh repo create zenobi-us/new-module \
  --template zenobi-us/bun-module \
  --public \
  --clone \
  --description "My awesome Bun module" \
  --homepage "https://example.com"

# Organization repository
gh repo create my-org/new-module \
  --template zenobi-us/bun-module \
  --public \
  --clone

Template Repository Structure

The zenobi-us/bun-module template provides:

• TypeScript configuration: Preconfigured tsconfig.json
• Mise integration: Task runner with build, test, format tasks
• Testing: Vitest test infrastructure
• Package configuration: Starter package.json with defaults
• Build tooling: Bundling with Bun's bundler
• Release automation: Release Please configuration for automated releases
• Documentation: README template, AGENTS.md, RELEASE.md
• Linting: ESLint and Prettier configured
• GitHub Actions: CI/CD workflows preconfigured

Setup Script Behavior

The setup.sh script runs non-interactively with these defaults:

After running setup.sh, you MUST manually edit package.json to update these values to your actual project details.

Common Workflows

Creating a Bun Package

# 1. Create repository from template
gh repo create zenobi-us/my-bun-package \
  --template zenobi-us/bun-module \
  --public \
  --clone \
  --description "My awesome Bun package"

# 2. Navigate to directory
cd my-bun-package

# 3. Run setup (applies defaults)
bash setup.sh

# 4. Edit package.json manually
# Update: name, description, author.name, author.email

# 5. Trust mise and build
mise trust
bun install
mise run build

# 6. Commit and push
git add package.json
git commit -m "chore: update package metadata"
git push -u origin main

Organization Package

# Create under organization
gh repo create my-org/shared-package \
  --template zenobi-us/bun-module \
  --public \
  --clone \
  --description "Shared Bun package for organization"

cd shared-package
bash setup.sh

# Edit package.json with org-scoped name:
# name: "@my-org/shared-package"
# ...

mise trust
bun install
mise run build
git add package.json
git commit -m "chore: update package metadata"
git push -u origin main

Private Package

# Create private repository
gh repo create zenobi-us/internal-package \
  --template zenobi-us/bun-module \
  --private \
  --clone \
  --description "Internal Bun package"

cd internal-package
bash setup.sh

# Edit package.json as needed
# ...

mise trust
bun install
mise run build
git add package.json
git commit -m "chore: update package metadata"
git push -u origin main

Troubleshooting

Template Repository Not Marked as Template

Problem: Could not clone: zenobi-us/bun-module is not a template repository

Solution:

# Mark repository as template
gh repo edit zenobi-us/bun-module --template

# Verify it's now a template
gh repo view zenobi-us/bun-module --json isTemplate

GitHub CLI Authentication

Problem: gh: Not authenticated

Solution:

# Authenticate with GitHub
gh auth login

# Verify authentication
gh auth status

Template Not Found

Problem: repository not found: zenobi-us/bun-module

Solution:

• Verify template repository exists and is accessible
• Check spelling of owner/repo
• Ensure template repository is public or you have access

Setup Script Fails

Problem: setup.sh: command not found or script errors

Solution:

# Verify file exists
ls -la setup.sh

# Make executable if needed
chmod +x setup.sh

# Run with bash explicitly
bash setup.sh

# Check Bun is installed
bun --version

Mise Trust Required

Problem: Config files in [...] are not trusted

Solution:

# Trust the mise configuration
mise trust

# Now run mise tasks
mise run build

Clone Directory Exists

Problem: destination path 'repo-name' already exists

Solution:

# Choose different name or remove existing directory
rm -rf repo-name

# Or use --clone flag without specifying directory
gh repo create owner/repo-name --template ... --clone

Build Fails After Setup

Problem: Build fails or dependencies missing

Solution:

# Ensure dependencies are installed
bun install

# Trust mise config if not done
mise trust

# Try build again
mise run build

# Check for specific errors
mise run build --verbose

Post-Setup Next Steps

After successful setup and package.json updates:

1. Verify package.json: Ensure all fields are correct

   cat package.json | jq '.name, .description, .author'
   

2. Install dependencies:

   bun install
   

3. Trust mise and build:

   mise trust
   mise run build
   

4. Verify build output:

   ls -la dist/
   # Should see: index.js, index.d.ts
   

5. Run tests (if any exist):

   mise run test
   

6. Commit customizations:

   git add package.json
   git commit -m "chore: update package metadata"
   git push origin main
   

7. Update README: Replace template content with actual documentation

8. Update AGENTS.md: Document how AI agents should interact with your package

9. Configure CI/CD: Review and customize GitHub Actions workflows in .github/workflows/

10. Start development: Begin implementing your package in src/

Integration with Other Tools

With mise

# Pin Bun version in project
mise use bun@latest

# Add to mise.toml tasks
[tasks]
setup = "bash setup.sh"
test = "bun test"
build = "bun run build"

With Git Workflows

# Create feature branch immediately
git checkout -b feat/initial-implementation

# Set up pre-commit hooks
bun add -D husky lint-staged

With Package Managers

The template works with:

• Bun (primary): bun install, bun add
• npm (compatible): npm install works but Bun recommended
• pnpm (compatible): pnpm install works as fallback

Best Practices

1. Mark template repo once: Use gh repo edit --template on first use
2. Use descriptive repo names: Choose names that clearly indicate purpose
3. Scope package names: Use @scope/name for clarity and namespace ownership
4. Update package.json immediately: Don't forget to edit after setup.sh runs
5. Trust mise before building: Required for running mise tasks
6. Commit metadata updates separately: Keep setup commit and metadata commit separate
7. Test immediately after setup: Verify mise run build passes
8. Update documentation early: Replace template placeholders with real content
9. Configure visibility intentionally: Public for open source, private for internal
10. Review generated files: Ensure AGENTS.md, README.md, and workflows fit your needs

Known Limitations

1. Non-interactive setup: The setup.sh script doesn't prompt for input; it uses defaults that you must manually update in package.json afterward
2. Manual package.json editing required: You must edit name, description, and author fields after running setup.sh
3. No validation: The script doesn't validate your manual edits to package.json
4. Mise trust required: You must explicitly trust the mise configuration before running tasks

Quick Start Summary

The complete workflow in commands:

# 1. Ensure template repo is marked as template (one-time setup)
gh repo edit zenobi-us/bun-module --template

# 2. Create and clone from template
gh repo create OWNER/NAME \
  --template zenobi-us/bun-module \
  --public \
  --clone \
  --description "Your plugin description"

# 3. Enter directory
cd NAME

# 4. Run setup (uses defaults)
bash setup.sh

# 5. Edit package.json manually - UPDATE THESE:
#    - name: "my-bun-package" → "@owner/actual-name"
#    - description: "A Bun package" → "Your description"
#    - author.name: "Your Name" → Your actual name
#    - author.email: "you@example.com" → Your actual email

# 6. Trust mise, install, and build
mise trust
bun install
mise run build

# 7. Commit updates and push
git add package.json
git commit -m "chore: update package metadata"
git push -u origin main

Critical: Steps 5-7 are REQUIRED because setup.sh uses placeholder values.
